Question

what is the atomicity of ice and rock salt​

Answer 1

Explanation:

Salty water has a lower freezing point than pure water. The water on the surface of salty ice is colder, so the ice feels colder than pure water ice.

Answer 2

Dear Student,

◆ Answer -

Atomicity of ice = 3

Atomicity of rock salt = 2

● Explanation -

Atomicity is the number of atoms in molecules of a substance.

• Ice is essentially water with molecular formula H2O. It has 2 H-atoms and 1 O-atom. Hence, ice has atomicity 3.
• Rock salt is essentially sodium chloride with molecular formula NaCl. It has 1 Na-atom and 1 Cl-atom. Hence, rock salt has atomicity 2.

Thanks dear. Hope this helps you...
